Letters Patent N 92,277, dated July 6, 186.9. v

The ichedulo referred to in these Letras Patent and making part of the lame.

' To all whom it 'may concern:

Be -it known that we', A. G. CUMBUNS'and J. R. OUMMINS, of McKinney, in the county of Collin, and State of Texas, have invented a. new and useful I n1- provement in Plows; and we do hereby declare that the following is a full, clear, and exaut'description well -as rcventcd from tnrnin f the driveiis seat bein r l C' also attached to said beams, as will be hereinafter more fully described.

1t consists ot' a plow-beam, having one or more removable plows, the front end of the said beam being attached to the frontaxle of any common farm-wagon, by passing the king-bolt of the said .axle through a hole in the front end ot' the beam, the said end heilig inserted between the bolster and axle, in the manner of a coupling or reach-pole.

lhe beam is provided with a'movable seat for a drivel', and is capable ot' being atixed at any suitable point in thc beam, in order to bring the weight ofthe driver over or away from the plows, according as the soil is heavy or light.

.In the drawings- V v A B is the beam,'having its front end B enlarged horizontally, and somewhat thinner than .the main body ofthe beam, for inserting between the front bol- -sterand axle of any com non wagon, and havingr a. hole, a, for the king-bolt, by whicnthe beamis attached to the front asie. v 1n practice we usually employ two plows, but more vorless may be used'it`desired.

.-1.010 are the plows.

D D, the standards of the samebwhich latter arey aiixed tothev beam by bolts i) and stay-rods, -orA braces d.

cc c c are bolts passingthrongh :standards and plows. l

The'stay-rods d pass through the standards, `and are.V lprovided with nuts e e, to give the standardsfthe proponi' f incline orangle for the best effect of? thleiplows.; -4 j l 4'iShedrivers scat E isatlixed tothe-'upper end'of a ,curved metal plate, or spring, Gfwhich isbent to bring its lower end to rest flatly upon the beam,to which it is attixed by a bolt, j, passing through it and the beam. v

There are a number of holes, g, along thev beam, for the purpose ot' shifting the seat to or from the plows, as the soil is heavy or light, for when the soil is light, the weight of the driver should be moved forward, so thathis whole weightv will not come upon the plows; but when the -soil isstit" and heavy, itiwill require the weight of the driver immediately over the plow, to cause them to keepr in the ground.

The seat can be adjusted to these extremes, or any intermediate point between them, and thus insure the efi'ective working of the plow in all kinds of' soil.

When a single plow only is to be used, the rear plow is taken ot, and the front plow shifted back to `he plage ofthe real plow, on the right side ofthe.

eam.

In the plan view, it will be observed'tfhat a certain contbrmation of the beam is requisite or desirable, toA afford the proper arrangement of the plows, and to brace the same; and it will also be obvious, that by,` continuing this iorm in the same manner, attachment may be afforded for a third plow in the rear end, to

` the left of the second plow, and we desire to be understood as 4not limiting our invention to the use of two plows only, as three or four may be employed without departing ii'om the spirit ofthe invention.

.liv means otourinvention,the heavy frame usually I required for gang-plows is dispensed with.

Again, the plows can be turned at the angles of the lield or furrows, without litting out the plows, but by simply turning thetcam and axle to which the plows are attached, in the usual manner f driving around-corners. v

These advantages permit the plowto be managed by a boy or other light person, as hewill not be re- .quired to litt out the plows inturning corners.'

.Having thus described our invention,

We cla-im as new, and desire to secure by Letters Pat-entf The plow-bea A, formed withvthe-frqnt, end B enlarged horizontally, aridA perforatedlfor' the, purpose specified, the4 samefbeing likewise provided withtho seat E, longitndinallyfadjustablq thereon,v by means of .the bolt f and holes and the adjustable standards D I2 and adjusting oes1d,'a.s herein set forth.
